Now the winter 2026 anime season is coming to an end, and incredible anime such as Jujutsu Kaisen, Oshi no Koand The Suitor: Beyond Journey's End will go off the air again. All that leaves some big shoes to fill in the spring 2026 season, and luckily, this season is up to the job with its delightful offerings. Titles like Re: Zero and The time I was reincarnated as a slime are all headliners, but fans must not underestimate other Spring titles, such as Welcome to Demon School! Iruma-kun.
This is one of the more underrated fantasy titles, and Welcome to Demon School! Iruma-kun is proof that fantasy still has some new ideas to offer. There's more to this oversaturated genre than self-indulgent power trips or exhausting world-building, as Welcome to Demon School! Iruma-kun often feels like My Hero Academia in a fancy font. It helps broaden the anime's appeal, and sometimes it barely even feels like fantasy at all. This anime returns for its fourth season, and the power levels, stakes, comedy, and power of friendship all reach new heights in the demonic Netherworld.

The third season of Welcome to Demon School! Iruma-kun featured some important developments for Iruma Suzuki and his classmates, with the Harvest Festival being the biggest of them. Many episodes were devoted to this incredible event for two main reasons: to show how far Abnormal Class has come with their training, and to play up the school aspect of this anime. It's a good reminder of that Welcome to Demon School! Iruma-kun is not the same as a power-fantasy sandbox, as the Iruma Suzuki is actually quite limited in comparison. Like it or not, he's a student at Babyl's school, so both he and the viewers might as well enjoy it. That includes all the fun ad growth found in events like the Harvest Festival.

Both the spirit and the distribution of the Harvest Festival promise to give shape to Welcome to Demon School! Iruma-kun Season 4 this spring. At first, Naberius Kalego was quite impressed with his students' performances in the Harvest Festival, but he still pushes them for more, which is his idea of tough love. Regardless of the students' recent rank upgrades, Kalego wants to see more promotions, most of all for the lower ranked students in the abnormal class. The solution: to perform well in the upcoming music festival.
Best Isekai anime with overpowered main characters
Overwhelmed protagonists are a staple of isekai anime, and the best series shows why this concept is so common.
This has many implications, starting with the idea that school events are now becoming the norm more than ever in Welcome to Demon School! Iruma-kunall with a demonic twist to keep things exciting and not too familiar in the high school anime genre. Trips to Walter Park or sleepovers were delightful, but school is the real focus here with back-to-back events like this. Game time is over as Iruma's classmates face relentless pressure to succeed, and the music festival is the key. There's no telling how the music festival will challenge its horned heroes, but fans can expect all kinds of wacky antics and comedy, all topped off with more power of friendship.
All this means Welcome to Demon School! Iruma-kunThe fourth season will have a dominant atmosphere of festive fun and creative expression, showing how far this anime's characters have come. Early on, the students at Babyls acted like the young demons they are, focusing on action and competition while terrifying the human Iruma with their ruthless ways. But Iruma had a positive impact on all of them, increasing everyone's confidence, happiness, and even the quality of their friendship. The school itself plays this up with the Music Festival, a time of creative expression instead of action. There certainly will be some demonic twist, but overall things are constructive and healthy at Babyls, and Season 4 promises to keep the good times rolling.

Season 3 of Welcome to Demon School! Iruma-kun had already gotten viewers pretty psyched for next season with the announcement of the music festival and the potential for more promotions or more use of bloodline magic, but that alone wasn't enough to end the adventure there. The anime packed another surprise that completely blindsided the viewers: the announcement that another classmate of theirs would also be promoted at the music festival. Iruma, Asmodeus Alice and the rest didn't even understand who Naberius Kalego was describing until they finally looked to the side and saw him.

Not all isekai protagonists are allowed to be reincarnated as heroines, as some find themselves as villains destined to be doomed in the end.
Funnily enough, Welcome to Demon School! Iruma-kun had given the last classmate plenty of cameos up until then, but he was a quiet, easy-to-miss student who didn't draw attention to himself in any way. He was hiding in plain sight the whole time, with only the most sharp-eyed viewers noticing him, and the anime didn't explain anything about who he was.
Finally, Welcome to Demon School! Iruma-kun shines the spotlight on Iruma's overlooked classmate, a little winged boy named Purson Soi. Season 4 promises to flesh out who Purson Soi is and what he can do in a class full of high-powered students, with the upcoming music festival being the perfect chance for him to wow viewers with his talents in an amazing way.
